Pollution of water resources is a widespread challenge across the globe which requires effective policy measures. However, in many instances, state institutions are weak in addressing these problems. One then wonders what alternative management regimes can be used in place of public policies. This study examined the willingness to pay (WTP) for the improvement of the Ankobra River, a mining-polluted river in the Western Region of Ghana, using the contingent valuation method.

Abstract

We use rich survey data to investigate the economic impact of a climate-friendly rice farming method known as the system of rice intensification (SRI) on the welfare of rain-dependent small-holder farmers in Tanzania. SRI reduces water consumption by half, which makes it a promising farming system in the adaptation to climate change in moisture-constrained areas, and it does not require flooding of rice fields, resulting in reduced methane emissions.
